Mass is how much "matter" something is.  Weight is this with respect to gravity.  Therefore, if you took a ball to the moon, its mass would not change because the amount of matter is unaffected but the weight will change because the Earth and the Moon have different gravitational pulls.

Hope this helps!!

The path difference will be 1571 nm

Now for the constructive interference, the formula is given

[tex]\rm dsin\theta==n\lambda[/tex]

here,

d = is the distance between slits.=060mm

θ = is the angle of diffraction=0.30 Degree

n = is the order of fringe=2

λ = is the path difference.

[tex]\lambda=\dfrac{(dsin\theta)}{n}[/tex] [tex]\lambda=\dfrac{(0.60\times10^{-3}\times sin(0.30)}{2} = 1.57\times10^{-6}[/tex]  

Thus path difference will be 1571 nm

From the AAS property of congruency the side ab≅ac in the isosceles triangle.

Congruency generally shows the similarities between two triangles or any other shape for the similarity of the two shapes they should have any three properties same like their three sides, Three angles or one angle two sides and so on.

Now for an Isosceles triangle abc given in the figure

[tex]\angle bad=\angle cad[/tex]

[tex]\angle abd=\angle acd[/tex]

[tex]ad=ad[/tex]   (common side)

So from the AAS property, the triangle [tex]\Delta bad=\Delta acd[/tex] are congruence

The side ab will also be equal to the side ac.

So from the AAS property of congruency is the side ab≅ac in the isosceles triangle.

Answer: (-1, 6)

Step-by-step explanation:

Use the midpoint formula:

(Xm, Ym) = ([x1 + x2]/2, [y2 + y1]/2)

(Xm, Ym) = ([2 + -4]/2, [6 + 6]/2)

(Xm, Ym) = (-2/2, 12/2)

(Xm, Ym) = (-1, 6)

The midpoint is (-1, 6)

we have to calculate the values ​​of A and B, so we have to:

[tex]A=100\\B=5[/tex]

Since the equation is:

[tex]R(X)=(500+ax)(50-bx)[/tex]

And the following information was given:

A school typically sells 500 yearbooks each year for $50 each.

The economics class discovers that they can sell 100 more yearbooks for every $5 decrease in price.

So knowing that by increasing 100 more books sold this is equal to A and the decrease in value is going to be equal to b.

[tex]R(X)=(500+100x)(50-5x)[/tex]

Answer:

$1020

Step-by-step explanation:

Since 15% is taken away, the total price would be $1,020. This means that the sales price is 85% of the price.

Step-by-step explanation:

300/20 × 3/3 = 900/60

* 60 sec is 1 min therefore you want to get 60 secs in the denominator. In order to get that, you need to multiply.

900/60 divided by 60/60 is 15/1.

So 300m/20sec = 900m/60sec = 900mpm

If we're to do the same for all then it would be:

30m/20sec = 90m/60sec = 90mpm

15m/20sec = 45m/60sec = 45mpm

3m/20sec = 9m/60sec = 9mpm

Answer: $38.16

Step-by-step explanation:

Finding total costs with sales tax is really quite simple. Here is the formula.

= $2.16

= 2.16 + 36

= $38.16

Hiking

Step-by-step explanation:

Given: Kayaking burns 4.5 calories per minute

The slope of the graph is 5

You can use rise over run to figure out the slope. Or you may have noticed the order pair (1,5)

This means hiking burns 5 calories per minute, which is greater than 4.5

Answer:

The answer is P(x)8x-1200

Step-by-step explanation:

The profit function for Andrew’s new product line will be P(x) = 2x - 1200. Then the correct option is A.

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.

The profit is given as,

Profit = Revenue function  - Cost function

Andrew has determined that the revenue and cost functions for a new product line at his business are given by these functions.

R(x) = 5x

C(x) = 1200 + 3x

Then the profit function for Andrew’s new product line will be

P(x) = R(x) - C(x)

P(x) = 5x - 1200 - 3x

P(x) = 2x - 1200

The profit function for Andrew’s new product line will be P(x) = 2x - 1200. Then the correct option is A.

Option second [tex]\rm (w-2.5)(w+2.5)[/tex] and option fourth  [tex]\rm (-4v-9)(-4v+9)[/tex]  are the products that result in a difference in squares

It is required to identify which products result in a difference of squares.

Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.

We know that:

[tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]

In option first:

[tex]\\\rm= (5z+3)(-5z-3)\\\rm =-(5z+3)(5z+3)\\\rm =-(5z+3)^2[/tex]

It is not the difference between squares.

In option second:

[tex]\rm = (w-2.5)(w+2.5)\\\rm = (w^2-2.5^2)[/tex] By using [tex]\rm (a^2-b^2)=(a+b)(a-b)[/tex]

It is the difference between squares.

Similarly, in option third:

[tex]\rm = (8g+1)(8g+1)\\\rm = (8g+1)^2[/tex]

It is not the difference between squares.

Similarly, in option forth:

[tex]\rm = (-4v-9)(-4v+9)\\\rm = (4v+9)(4v-9)\\\rm = (4v)^2-9^2[/tex]

It is the difference between squares.

Similarly, in option fifth:

[tex]\rm = (6y+7)(7y-6)\\\rm = 42y^2+13y-42[/tex]

It is not the difference between squares.

Similarly, in option sixth:

[tex]\rm = (p-5)(p-5)\\\rm = (p-5)^2[/tex]

It is also not the difference between squares.

Thus, option 2 and option 4 are correct.

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Adjacent means 'next to'. Angles 1 and 4 are next to angel 3, on the top and to the right.

Based on the vertical angles theorem we can assume that the angles are equal to each other so:

7x-25 = 4x + 2

Now find the value of x

Subtract 4x to both sides

3x - 25 = 2

Add 25 to both sides

3x = 27

Divide by 3 to isolate x

x = 7

Complete question is;

Vickie conducts a survey of home builders to determine the average cost of building a new home. She samples 10 home builders who are building in the town in which she lives. Under which conditions will her sample be a representative sample? Select two options:

A) The builders were chosen at random.

B) The population included only builders who build in Vicki’s town.

C) The population included builders who build homes in any town.

D) The population included builders who do not build homes in Vicki’s town.

E) The builders were referred to Vicki by the realtor who will be selling the houses.

Answer:

Options A & B are correct.

A) The builders were chosen at random.

B) The population included only builders who build in Vicki’s town.

Step-by-step explanation:

Looking at the question, we see that Vickie wanted to determine the cost of building a new home in the town in which she lived. Now, she sampled builders who are building in the town in which she lives and thus, it makes the sample more representative.

However, the random method of choosing the builders would help to remove any lingering biases that may arise.

Thus, we can conclude that the builders were chosen at random and that it included only those who build in her town.

Thus, options A & B are correct.

Answer:

A)The builders were chosen at random., B)The population included only builders who build in Vicki’s town.

Question 3: 2.7 hours

Question 4: 2.3 hours

Step-by-step explanation:

Question 3:

Time taken by 1st delivery driver = t1 = 6 hours

Time taken by 2nd delivery driver = t2= 5 hours

Time together = T

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ t1 } + \dfrac{ 1 }{ t2 }}[/tex]

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ 6 } + \dfrac{ 1 }{ 5 }}[/tex]

[tex]{\dfrac{ 1 }{ T } = 0.166+0.2 = 0.366}[/tex]

[tex]{T = \dfrac{ 1 }{ 0.366 } = 2.732}[/tex]

Rounded to the nearest tenth: 2.7 hours

Question 4:

The first valve takes 4 hours to completely drain = t1

[tex]\mathrm{Rate\:for\:first\:valve\:will\:be\:\dfrac{1}{4}\:per\:hour}[/tex]

The second valve taken 5.25 hours to completely drain = t2

[tex]\mathrm{Rate\:for\:second\:valve\:will\:be\:\dfrac{1}{5.25}\:per\:hour}[/tex]

Combined time = T

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ t1 } + \dfrac{ 1 }{ t2 }}[/tex]

[tex]{\dfrac{ 1 }{ T } = \dfrac{ 1 }{ 4 } + \dfrac{ 1 }{ 5.25 }}[/tex]

Step-by-step explanation:

to find out this question you should first make 66 2/3% into a fraction

that is 99.99...% percent which is also 2/3

you can then divide 8 men by 2/3

that is 8/1 divided by 2/3 which is essentially 8/1 * 3/2

that turns into 12

that means there are 12 crew members
